Introduction

Backplane connectors are an integral part of the electronic industry and are widely used in a multitude of applications. Hard metric and standard connectors are particularly popular when it comes to backplane connectors, and PCN21B-125PB-2W is a perfect example of this type. In this article, we will be describing what PCN21B-125PB-2W is, as well as its application field and working principle.

What is PCN21B-125PB-2W?

PCN21B-125PB-2W is a type of hard metric backplane connector. It has a connection type of board-to-board, and is constructed with an isolating insulator. It has an impedance of 100 Ohm and is rated for 2W of power. PCN21B-125PB-2W has a pair of mating halves that snap together and provide a secure connection. The front and back of the connector are designed with a unique locking system that ensures a tight fit between the two halves.

Application Field

PCN21B-125PB-2W is primarily used in electronic applications as a backplane connector. It is particularly popular in the aerospace and defense industry, where its hard metric design makes it ideal for high tension connections. The connector is also widely used in medical equipment and instrumentation systems, where its low profile design and reliability make it an ideal choice.

Working Principle

The working principle of PCN21B-125PB-2W is fairly simple. To establish a connection, the two mating halves of the connector are snapped together until they form a tight fit. Then, the two halves are held in place using the locking system on the front and back of the connector. This ensures a secure connection and prevents the connector from being accidentally unplugged. The pins have a 100 ohm impedance, meaning that they are capable of carrying up to 2W of power.

Conclusion

PCN21B-125PB-2W is a hard metric backplane connector that is widely used in a variety of applications. Its high impedance and 2W power rating make it an ideal choice for aerospace and defense applications, as well as medical equipment and instrumentation systems. Its unique locking system ensures a secure connection between the two halves of the connector, preventing it from being accidentally unplugged.
